This is just a place holder for my Fargduino project. The project consist of a Fuel / Air ratio gauge for gas engines based on the Arduino. The unit will be able to process the signal for up to two O2 sensors.
It will consist of a Interchangeable display head for single and dual O2 sensors and a control module. The Single O2 sensor head have a circle of 20 Led's and a 4 digit 7 segment display in the middle. The Dual O2 head will have just two 4 digits 7 segment display. The 7 segment display on both heads will display the FAR and Voltage of the O2 sensors and in the single head the LED's will give a visual reference point of the FAR.
The control module will handle either display by just placing or removing a jumper. For those O2 sensor that have a heater core the control module will be able to check for continuity of the heater before applying power to it.
All of it is built on a breadboard at the moment but as I start receiving the PCB's and parts I'll be posting photos of the project. :)
